Patent GB-2154374-A (GB)
Title: Miniature transformers and inductors
Inventor: TYACK KENNETH
IPC: H01F27/06
Filed: 1984-02-15
Abstract: A miniature transformer has a wound ferrite core (2) secured to a thick film circuit (1) which provides the external connection terminals for the transformer. Securement is made using a glass-filled nylon cup-shaped part (10). The wound core is housed in the cup-shaped part and the underside of the cup-shaped part is glued to the substrate (1). A closure lid (6) holds the wound core in the cup (10). The cup-shaped part eliminates magneto-strictive reaction which would otherwise be caused if the core (2) were glued directly to the substrate. Modifications are described to the housing. <IMAGE>

Title: Method and apparatus for amplitude control of varying parameters
Inventor: AGUILAR RONALDO
IPC: H02H7/00
Filed: 1984-03-01
Abstract: The amplitude of a varying parameter is controlled by sensing the rise or fall in the amplitude of the parameter, determining therefrom the rate of rise or fall (p, q) and, when the rate is indicative that an amplitude (P, Q) is developing which is greater or lesser as the case may be than a predetermined level, then eliminating, or modulating by attenuation or amplification as the case may be, the amplitude to prevent an amplitude above or below the predetermined level as the case may be from developing. The parameter may be electrical power, current or voltage, or torque or acceleration, especially in a three-phase induction motor. <IMAGE>

Patent GB-2170292-A (GB)
Title: Conveyor belt fastener
Inventor: BRADSHAW NORMAN FRANCIS
IPC: F16G3/04
Filed: 1985-12-20
Abstract: With heavy duty conveyor belts it is known to provide U-shaped plates of a width such that two staples can extend through appropriate holes in each plate, to secure the plate to the end of the conveyor. However, the closely spaced, in-line relationship of the staples generates two lines of potential weakness across the belt, with a third line of potential weakness caused by the square ends of the U-shaped plates cutting into the belt as it passes round drive and return drums. The object of the invention is to avoid these disadvantages by a construction comprising a U-shaped plate 1, there being at least two longitudinally disposed pairs of holes 5 in each end of the plate, to receive a corresponding number of staples, each longitudinal pair of holes being longitudinally offset with respect to the immediately adjacent longitudinal pair of holes and whereby the corresponding holes of adjacent pairs lie in a different transverse plane. The ends (8) of each U-shaped plate are inclined to avoid a continuous line across the belt where the belt can be cut, to eliminate the third line of potential weakness of the prior art constructions. <IMAGE>

Patent GB-2187867-A (GB)
Title: Feedback control system
Inventor: STEWART ARCHIE SHAW
IPC: G05B11/06
Filed: 1987-03-12
Abstract: A feedback control system for controlling the velocity or (as shown) position of a member 12 uses two control loops which are interlinked by lines 20,21 and also by a control line 16 which responds to the force applied to an input member 10, the resulting system thus giving a sense of feel via a motor 36 to the input member 10 without using a force transducer at the output member. The input demand signal on line 20 is directly proportional to the output position or output velocity. Similarly, the output demand signal on line 21, or the derivative of the output demand signal for velocity control, is directly proportional to the position of the input. Velocity feedback loops 34,39 may be provided. Desirably the output position controller (29) operates under proportional control, and the input position controller operates under PID control. The system may be used to control a robot hand e.g. in nuclear, deep sea or other hostile environments, or a wheelchair. <IMAGE>

Patent GB-2210627-A (GB)
Title: Low temperature laundry detergents
Inventor: WILLIAMSON JOHN PETER HUGH
IPC: C11D3/12
Filed: 1988-08-17
Abstract: The performance of conventional sodium perborate-based domestic detergent powders, particularly at cool water temperatures of about 30 DEG C, is enhanced by incorporation of boronated felspathoids which may be pretreated with small amounts (usually less than 0.5% by weight) of metal salts such as copper sulphate or ferrous sulphate. These prepared reagents are added to a detergent "concentrate" to form about one third of the total bulk, or used in whole or partial replacement of any zeolite already incorporated in the commercial formulation. The reagents function partly by a direct catalytic decomposition of the perborate via a bleaching mode, partly by interaction with residual body perspiration which re-ionises the metal then inducing ion-catalysed decomposition of the perborate. The beneficial effects are apparent on treated garments as improved "freshness", a "fuller" handle on cottons, and marked "antistatic" effect on sythetic fabrics.
